All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As a latest computer input device, the touch screen is the simplest, convenient and natural man-machine interaction mode at present. The multimedia interactive device gives the multimedia a brand-new appearance and is a brand-new multimedia interactive device with great attractiveness. The method is mainly applied to inquiry of public information, leadership office, industrial control, military command, electronic games, song and dish ordering, multimedia teaching, real estate pre-sale and the like.
Referring to fig. 1, a block diagram of a terminal according to an exemplary embodiment of the present application is shown. A terminal in the present application may include one or more of the following components: a processor 110, a memory 120, an input device 130, an output device 140, and a bus 150. The processor 110, memory 120, input device 130, and output device 140 may be connected by a bus 150.
The memory 120 may be divided into an operating system space, where an operating system runs, and a user space, where native and third-party applications run. In order to ensure that different third-party application programs can achieve a better operation effect, the operating system allocates corresponding system resources for the different third-party application programs. However, the requirements of different application scenarios in the same third-party application program on system resources are different, for example, in a local resource loading scenario, the third-party application program has a higher requirement on the disk reading speed; in the animation rendering scene, the third-party application program has a high requirement on the performance of the GPU. The operating system and the third-party application program are independent from each other, and the operating system cannot sense the current application scene of the third-party application program in time, so that the operating system cannot perform targeted system resource adaptation according to the specific application scene of the third-party application program.
The input device 130 is used for receiving input instructions or data, and the input device 130 includes, but is not limited to, a keyboard, a mouse, a camera, a microphone, or a touch device. The output device 140 is used for outputting instructions or data, and the output device 140 includes, but is not limited to, a display device, a speaker, and the like. In one example, the input device 130 and the output device 140 may be combined, and the input device 130 and the output device 140 are touch display screens for receiving touch operations of a user on or near the touch display screens by using any suitable object such as a finger, a touch pen, and the like, and displaying user interfaces of various applications. The touch display screen is generally provided at a front panel of the terminal. The touch display screen may be designed as a full-face screen, a curved screen, or a profiled screen. The touch display screen can also be designed to be a combination of a full-face screen and a curved-face screen, and a combination of a special-shaped screen and a curved-face screen, which is not limited in the embodiment of the present application.
In addition, those skilled in the art will appreciate that the configurations of the terminals illustrated in the above-described figures do not constitute limitations on the terminals, as the terminals may include more or less components than those illustrated, or some components may be combined, or a different arrangement of components may be used. For example, the terminal further includes a radio frequency circuit, an input unit, a sensor, an audio circuit, a wireless fidelity (WiFi) module, a power supply, a bluetooth module, and other components, which are not described herein again.
In the embodiment of the present application, the main body of execution of each step may be the terminal described above. Optionally, the execution subject of each step is an operating system of the terminal. The operating system may be an android system, an IOS system, or another operating system, which is not limited in this embodiment of the present application.
The terminal of the embodiment of the application can also be provided with a display device, and the display device can be various devices capable of realizing a display function, for example: a cathode ray tube display (CR), a light-emitting diode display (LED), an electronic ink panel, a Liquid Crystal Display (LCD), a Plasma Display Panel (PDP), and the like. The user can view information such as displayed text, images, video, etc. using the display device on the terminal 101. The terminal may be a smart phone, a tablet computer, a gaming device, an AR (Augmented Reality) device, an automobile, a data storage device, an audio playing device, a video playing device, a notebook, a desktop computing device, a wearable device such as an electronic watch, an electronic glasses, an electronic helmet, an electronic bracelet, an electronic necklace, an electronic garment, or the like.
In the terminal shown in fig. 1, the processor 110 may be configured to call an application program stored in the memory 120 and specifically execute the touch screen ghost point identification method according to the embodiment of the present application.
When the capacitive touch screen acquires the coordinate data of the touch point and the touch area corresponding to the touch point, the capacitive touch screen can detect whether the coordinate data is acquired and whether the contact area is larger than a preset area. When the capacitive touch screen detects that the coordinate data is acquired and the contact area is larger than the preset area, the capacitive touch screen can determine that the touch point is not a ghost point. At this time, the capacitive touch screen drives the corresponding connection device for the touch point, so that the display screen of the terminal can perform corresponding operation for the touch point.
In the following method embodiments, for convenience of description, only the main execution body of each step is described as a terminal.
The touch screen ghost point identification method provided by the embodiment of the present application will be described in detail below with reference to fig. 2 to 8. The execution body of the embodiment shown in fig. 2-8 may be, for example, a terminal.
Referring to fig. 2, a schematic flow chart of a touch screen ghost point identification method is provided in the present embodiment. As shown in fig. 2, the method of the embodiment of the present application may include the following steps S101 to S104.
And S101, acquiring coordinate data of the touch point based on the received interrupt instruction.
According to some embodiments, the capacitive touch screen of the terminal is operated using current sensing of a human body. When the capacitive touch screen detects an interrupt instruction input by a user, the capacitive touch screen may drive the corresponding connection device so that the corresponding connection device may perform a corresponding operation. The interrupt instruction may refer to, for example, a click instruction of a user on the capacitive touch screen by using a finger belly received by the capacitive touch screen. However, when the palm of the user or the hand-held conductor is close to the capacitive touch screen instead of being touched, the capacitive touch screen can also receive a terminal instruction, which causes malfunction of the capacitive touch screen. The capacitive touch screen of the embodiment of the present application includes, but is not limited to, a surface capacitive touch screen and a projected capacitive touch screen.
It is easy to understand that when the capacitive touch screen receives the interrupt instruction, the capacitive touch screen can establish a coordinate system. Based on the established coordinate system, the capacitive touch screen can acquire coordinate data of the touch point. Fig. 3 shows an exemplary schematic diagram of a terminal interface according to an embodiment of the present application. As shown in fig. 3, a coordinate system established by the capacitive touch screen of the embodiment of the present application may be as shown in fig. 3. The capacitive touch screen can also establish a coordinate system before receiving an interrupt instruction.
Optionally, after the coordinate system is established on the capacitive touch screen, when the capacitive touch screen detects a touch instruction on the capacitive touch screen, the capacitive touch screen may receive an interrupt instruction. When the capacitive touch screen receives the terminal command, the coordinate data acquired by the capacitive touch screen to the touch point may be [ x5, y10], for example.
And S102, acquiring a touch area corresponding to the touch point.
According to some embodiments, when the capacitive touch screen acquires coordinate data of a touch point, the capacitive touch screen may acquire a touch area corresponding to the touch point. For example, the capacitive touch screen may obtain the touch area corresponding to the touch point by methods such as detecting a capacitance value of the capacitive touch screen and a pressure value of the capacitive touch screen.
It is easy to understand that, for example, each time a user clicks or presses on the capacitive touch screen with a finger, the actual contact area is not a single point but an area, so the touch area is usually coordinate data of an area enclosed by a plurality of pixel points, that is, the area of the area enclosed by the pixel points.
Optionally, when the capacitive touch screen receives the interrupt instruction, the capacitive touch screen may further obtain fingerprint information on the screen. The capacitive touch screen can determine the area where the fingerprint information is acquired as the touch area corresponding to the touch point. The touch area acquired by the capacitive touch screen may be zero, for example, and the touch area may also be 1 square centimeter, for example.
S103, when the coordinate data are not acquired or the contact area is smaller than the preset area, determining that the touch point is a ghost point.
According to some embodiments, fig. 4 is a scene schematic diagram illustrating a touch screen ghost point identification method according to an embodiment of the present application. As shown in fig. 4, the ghost point refers to a touch point where the user does not touch the capacitive touch screen, but the capacitive touch screen detects the user touch. The number of the ghost points may be one or more.
It is easy to understand that, when the capacitive touch screen acquires the coordinate data of the touch point and the touch area corresponding to the touch point, the capacitive touch screen may detect whether the coordinate data is acquired and whether the contact area is smaller than a preset area. When the capacitive touch screen detects that the coordinate data is not acquired or the contact area is smaller than the preset area, the capacitive touch screen may determine that the touch point is a ghost point. At this time, the capacitive touch screen does not drive the corresponding connection device for the touch point, so that the display screen of the terminal does not perform corresponding operation for the touch point.
According to some embodiments, the predetermined area of the capacitive touch screen arrangement may be, for example, 0.1 square centimeters. When the coordinate data of the a touch point acquired by the capacitive touch screen is [ x5, y10], for example, the contact area corresponding to the a touch point may be 0. When the capacitive touch screen detects that the coordinate data of the touch point A is acquired, but the contact area corresponding to the touch point A is smaller than the preset area, the capacitive touch screen cannot drive the connecting device corresponding to the touch point A.
Optionally, when the capacitive touch screen acquires the coordinate data of the touch point and the touch area corresponding to the touch point, the capacitive touch screen may further detect whether the coordinate data is acquired, whether the format of the coordinate data conforms to a preset format, and whether the contact area is 0. When the capacitive touch screen detects that the coordinate data is not acquired, the format of the coordinate data does not conform to the preset format, or the contact area is 0, the capacitive touch screen may determine that the touch point is a ghost point.
According to some embodiments, when the capacitive touch screen acquires the coordinate data of the touch point and the touch area corresponding to the touch point, the capacitive touch screen may detect whether the coordinate data is acquired and whether the contact area is larger than a preset area. When the capacitive touch screen detects that the coordinate data is acquired and the contact area is larger than the preset area, the capacitive touch screen can determine that the touch point is not a ghost point. At this time, the capacitive touch screen drives the connecting device corresponding to the touch point, so that the display screen of the terminal can perform corresponding response operation aiming at the touch point.
It will be readily appreciated that the predetermined area of the capacitive touch screen arrangement may be, for example, 0.5 square centimeters. When the coordinate data of the a touch point acquired by the capacitive touch screen is [ x5, y10], for example, the contact area corresponding to the a touch point may be 1 square centimeter. When the capacitive touch screen detects that the coordinate data of the touch point A is acquired, and the contact area corresponding to the touch point A is larger than the preset area, the capacitive touch screen can drive the connecting device corresponding to the touch point A.
The embodiment of the application provides a touch screen ghost point identification method, which is characterized in that coordinate data of a touch point and a touch area corresponding to the touch point are obtained based on a received interrupt instruction, and the touch point can be determined to be a ghost point when the coordinate data is not obtained or the contact area is smaller than a preset area. Therefore, according to the technical scheme of the embodiment of the application, when the capacitive touch screen does not acquire coordinate data or the contact area is smaller than the preset area, the touch point can be determined to be a ghost point, the capacitive touch screen cannot drive a corresponding connecting device, the response operation of the terminal to the ghost point can be reduced, and the use experience of a user can be improved.
Referring to fig. 5, a schematic flow chart of a touch screen ghost point identification method is provided in the present embodiment. As shown in fig. 5, the method of the embodiment of the present application may include the following steps S201 to S205.
S201, receiving an interrupt instruction.
According to some embodiments, the capacitive touch screen may receive a terminal instruction when the capacitive touch screen detects a touch on the capacitive touch screen.
The specific process is as described above, and is not described herein again.
S202, scanning the touch screen by adopting a preset scanning algorithm to obtain coordinate data of the touch point.
According to some embodiments, when the capacitive touch screen receives the interrupt instruction, the capacitive touch screen may scan the touch screen by using a preset scanning algorithm. The preset scanning algorithm may include, for example, a scanning direction, a scanning time, a scanning speed, and the like of the capacitive touch screen.
It is easy to understand that when the capacitive touch screen receives the interrupt instruction, the capacitive touch screen establishes a coordinate system according to a preset method. After the capacitive touch screen establishes the finished coordinate system, the capacitive touch screen may scan the capacitive touch screen according to a preset scanning direction and a preset scanning speed, and the coordinate data of the touch point acquired by the capacitive touch screen may be [ x8, y9], for example.
And S203, acquiring the capacitance value of the touch point.
According to some embodiments, a capacitive touch screen is provided with a capacitive detection device. The capacitance detection means may be, for example, a capacitance sensor. When the capacitive touch screen receives the interrupt instruction, the capacitive touch screen can acquire the capacitance value of the touch point through the capacitance detection device. For example, when the capacitive touch screen receives an interrupt instruction, the capacitance of a touch point of the capacitive touch screen changes, so that the frequency of an oscillator connected with the capacitive touch screen changes, and therefore the capacitive touch screen can determine the capacitance value of the touch point by measuring the frequency change. The capacitance value acquired by the capacitive touch screen may be 1pf, for example.
And S204, acquiring the touch area based on the capacitance value.
According to some embodiments, when the capacitive touch screen acquires a capacitance value of a touch point, the capacitive touch screen may acquire a touch area based on a correspondence between the capacitance value and the touch area. The correspondence may be, for example, a correspondence stored in advance in a memory of the capacitive touch panel, and the correspondence may also be, for example, a calculation relationship between a capacitance value and a touch area.
It is easily understood that the correspondence may be, for example, a correspondence stored in advance in a memory of the capacitive touch screen. When the capacitance value of the touch point acquired by the capacitive touch screen is 1pf, the touch area acquired by the capacitive touch screen may be 0.01 square centimeter, for example.
It is easy to understand that please refer to fig. 6, which provides a flowchart of a touch screen ghost point identification method according to an embodiment of the present application. As shown in fig. 6, the method of the embodiment of the present application may include the following steps S301 to S302. S301, sending the coordinate data to a terminal processor; s302, when the feedback information of the corresponding operation of the coordinate data by the user is not received within the preset time, determining that the touch point is a ghost point.
According to some embodiments, when the capacitive touch screen acquires coordinate data of a touch point, the capacitive touch screen may drive a connection device corresponding to the coordinate data. The connecting means may be, for example, a terminal processor. The terminal processor can perform corresponding operation on the coordinate data. And in a preset time, when the capacitive touch screen does not receive feedback information of the corresponding operation of the user on the coordinate data, determining that the touch point is a ghost point.
Alternatively, the preset time set by the terminal may be, for example, 5 seconds. When the coordinate data of the touch point acquired by the capacitive touch screen may be [ x8, y9], for example, the capacitive touch screen may drive the connection device corresponding to the coordinate data. The connection means may be responsive to an operation corresponding to the coordinate data. The operation corresponding to the coordinate data may be, for example, opening a WeChat. Within a period of 5 seconds. When the capacitive touch screen does not receive feedback information of the user on the opening WeChat, the capacitive touch screen can determine that the touch point is a ghost point. The feedback information of the user for opening the WeChat includes but is not limited to click feedback information, text feedback information, voice feedback information and the like.
It is easy to understand that please refer to fig. 7, which provides a flowchart of a touch screen ghost point identification method according to an embodiment of the present application. As shown in fig. 7, the method of the embodiment of the present application may include the following steps S401 to S403. S401, acquiring pressure change data of the touch screen; s402, acquiring a contact area based on the pressure change data.
According to some embodiments, when the capacitive touch screen acquires coordinate data of a touch point, the capacitive touch screen may acquire pressure change data of the touch screen. The capacitive touch screen may acquire a contact area based on pressure change data. The capacitive touch screen may acquire the touch area based on the correspondence between the pressure change data and the touch area. The correspondence may be, for example, a correspondence stored in advance in a memory of the capacitive touch panel, and the correspondence may also be, for example, a calculation relationship between pressure change data and a touch area.
It is to be understood that the correspondence may also be a calculation relationship between the pressure change data and the touch area, for example. When the capacitive touch screen acquires the pressure change data of the touch point as 10-9At Pa, the touch area obtained by the capacitive touch screen based on the calculation relation between the pressure change data and the touch area may be, for example, 0.01 square centimeter.
It is easy to understand that please refer to fig. 8, which provides a flowchart of a touch screen ghost point identification method according to an embodiment of the present application. As shown in fig. 8, the method of the embodiment of the present application may include the following steps S501 to S502. S501, acquiring a polygon of a contact surface with a touch point as a center; s502, determining the contact area by calculating the area of the polygon.
According to some embodiments, when the capacitive touch screen acquires coordinate data of a touch point, the capacitive touch screen may acquire a polygon of a contact surface centered on the touch point. The capacitive touch screen may determine the contact area by calculating the area of a polygon. The polygons include, but are not limited to, regular and non-regular polygons, convex and concave polygons, and the like.
It is easily understood that when the capacitive touch screen acquires coordinate data of a touch point, a polygon of a contact surface with the touch point as a center acquired by the capacitive touch screen may be a square, for example. The touch point is the intersection point of the diagonals of the square. The side length of the square may be 0.1 cm, for example, and thus the area of the polygon calculated by the capacitive touch screen may be 0.01 cm. The contact area captured by the capacitive touch screen may be 0.01 square centimeters.
And S205, stopping responding to the interrupt instruction when the coordinate data is not acquired or the contact area is smaller than the preset area.
According to some embodiments, when the capacitive touch screen acquires the coordinate data of the touch point and the touch area corresponding to the touch point, the capacitive touch screen may detect whether the coordinate data is acquired and whether the contact area is smaller than a preset area. When the capacitive touch screen detects that the coordinate data is not acquired or the contact area is smaller than the preset area, the capacitive touch screen may stop responding to the interrupt instruction. At this time, the capacitive touch screen does not drive the corresponding connection device for the touch point, so that the display screen of the terminal does not perform corresponding operation for the touch point. According to the technical scheme of the embodiment of the application, the influence of ghost points on the terminal can be reduced, and the using effect of a user can be improved.
